Vesnalui [34]

Answer:

1) James brother is 10-x years old

2) James was 3 years ago x-3 years old

3) James brother was 3 years ago 7-x years old

4) 3(x-3)=7-x

5) James is 4 years old, his brother is 6 years old

Step-by-step explanation:

3) 10 - x - 3 = 7 - x

5) 3* James age 3 years ago = James brothers age 3 years ago

<=> 3*(x-3) = 7-x

<=> 3x - 9 = 7 - x

<=> 4x = 16

<=> x = 4

LenaWriter [7]

Answer:

$21x^{7}y^{11}$

Step-by-step explanation:

Remove the parentheses and take out the constansts.

$(7 x 3) x^{2} x^{5} y^{3} y^{8}$

Simplify 7 x 3 to 21.

$21x^{2} x^{5} y^{3} y^{8}$

Use the product rule: $x^{a} x^{b} = x^{a + b}$

$21x^{2 + 5}y^{3+8}$

Simplify 2+5 to 7.

$21x^{7}y^{3+8}$

Simplfiy 3 + 8 to 11.

$21x^{7}y^{11}$
